ATEN CS1944DP 4-Port USB 3.0 4K DisplayPort Dual Display KVMP Switch
Part numberCS1944DP
The short answer
The ATEN CS1944DP is a KVM switch for four computers with DisplayPort video, aimed at a mini PC owner who runs several machines from one desk. The name calls it a dual display, 4K, USB 3.0 KVMP switch, so each machine you connect needs a DisplayPort output.
Specifications
It handles four computers, enough for a small group of mini PCs sharing one desk setup. Video travels over DisplayPort, and the name promises dual display output at 4K. USB 3.0 in the name points to USB 3.0 connections for your peripherals. The part number is CS1944DP, which is useful when you check the maker's page.

Which mini PCs it fits
The rule is simple: the switch takes video over DisplayPort, so a mini PC needs a DisplayPort output to connect. The ACEMAGIC K1 (Intel), ASUS NUC 14 Performance, Beelink SER8 and Dell Pro Max Micro FCM2250 each connect through a DisplayPort output. The ASUS ExpertCenter PN65, Apple Mac Studio (M5 Max) and BMAX MaxMini B4 Ultra have no DisplayPort output, so they do not fit. For the GMKtec EVO-X3 and MINISFORUM AtomMan G7 Pro, we have not confirmed the fit, because we do not know which DisplayPort outputs they have.
Checked against every mini PC sold on amazon.com, from the specifications we hold for each machine.

Before you buy
Before you buy, check that every machine you plan to connect has a DisplayPort output. Machines without one, like the three named above, will not connect. ATEN does not state the switch's port layout, so confirm it on the maker's page.
Common questions
Does it work with a mini PC that has no DisplayPort output?
No. The switch takes video over DisplayPort, so machines without that output, such as the ASUS ExpertCenter PN65 and the BMAX MaxMini B4 Ultra, do not fit it.
How many mini PCs can share one switch?
It is built for four computers, so four mini PCs with DisplayPort outputs can share one switch and one desk setup.
Is the fit confirmed for the GMKtec EVO-X3?
Not confirmed. We do not know which DisplayPort outputs the GMKtec EVO-X3 or the MINISFORUM AtomMan G7 Pro have, so we have not confirmed that either one fits.
